The objective is to keep the environment healthy and select products for cleaning your homes and pet areas that are "non-toxic" and "eco-safe". According to the US EPA, levels from indoor pollutants can be two to more than 100 times higher than outdoors and the number one culprit is cleaning products. Avoid phosphates, chlorine, artificial fragrances and colors. Look for products that are "petroleum free" and use grain alcohol instead of toxic butyl cellosolve and borax instead of bleach.
